3 Operating the Power Supply Locally

Power Supply OK Signal

The Power Supply OK signal on the J1 connector indicates a fault condition in the power supply. J1 pin 16 is a TTL output signal. Pins 2 and 3, which are connected internally, are the signal common. All pins are optically isolated from the power supply output. With no fault, Power Supply OK is high, with a maximum source current of 2mA. When a fault occurs, Power Supply OK is low, with a maximum sink current of 1mA. The following faults set this signal low:

Over-voltage protection Over-current protection Over-temperature protection AC line failure

Enable/Disable signal true Shut Off signal true Remote interface failure Output turned off

Daisy-Chained Output Shut-down

It is possible to configure a multiple power supply system to shut down all the units when a fault condition occurs in one of the units. SW1 setup switch 5 must be in the Down position to enable the daisy- chain operation. Other switches are unaffected by this setting.

If a fault occurs in one unit, its Power Supply OK signal is set low and its display will indicate the fault. The other units shut off with their displays indicating SO. When the fault condition is cleared, all units will recover according to their Safe-Start or Auto-Restart settings.

The following figure shows three units daisy-chained - the same connection method can be used with additional units. The Shut Off and Power Supply OK signals are referenced to Chassis Common (J1 pins 2 and 3).
